Description

The South African Geomatics Instituteâ€™s Northern Provinces Branch will be hosting a workshop on Survey Specifications for Non-Surveyors at the Pumulani Lodge on 30 July 2009.

This workshop will be geared towards the needs of inter alia, Mining Companies, Construction Engineers, Architects, Geologists, Consulting Engineers and Town and Regional Planners who have to make use of the services of Surveyors for the execution of their various projects. Inadequate survey specifications could lead to costly mistakes and the waste of valuable time. This workshop will not only facilitate the drafting of survey specifications but will also ensure that both the client and surveyor will get the optimum value as the different technologies that could be used, depending on the type of project will be dealt with.

The following topics will be dealt with during the workshop:

ïƒ˜ Introduction: An overview of common mistakes, inadequate specifications, accuracies required for the end- result;
ïƒ˜ Lidar Surveys: description of the technology; what it is used for; advantages and disadvantages of the technology; accuracies that can be achieved; elements that should be in the specification
ïƒ˜ Aerial Surveys: description of the technology; what it is used for; advantages and disadvantages of the technology; accuracies that can be achieved; elements that should be in the specification
ïƒ˜ 3D Laser Surveys: description of the technology; what it is used for; advantages and disadvantages of the technology; accuracies that can be achieved; elements that should be in the specification
ïƒ˜ Global Positioning Systems(GPS): description of the technology; what it is used for; advantages and disadvantages of the technology; accuracies that can be achieved; elements that should be in the specification;
ïƒ˜ Reflectorless(Standard) Survey Equipment: description of the technology; what it is used for; advantages and disadvantages of the technology; accuracies that can be achieved; elements that should be in the specification
ïƒ˜ Survey Methodology: what is a survey system; different survey systems; the South African Grid-system; WGS84, spheroid, geoid; why does GPS heights have to be adjusted; geoid modelling and geo-referencing; Survey procedure; Map Scale; Control Survey; benchmarks, etc.
ïƒ˜ Elements of an adequate Survey Specification: Purpose of the survey; qualifications/experience of the surveyor; accuracies to be achieved; control survey; benchmarks; Survey-topographic-density of points; format of data output, etc,
